Rise of the Unlimited.
The setting for this story is Rifts Earth, North America, roughly five years after the Siege of Tolkien. The CS has grown  in stability greatly after the fall of its main opponent. While they haven't spread much further, they are very comfortable with the state of their empire. However, that doesn't mean that it has gotten any safer. In fact, things have gotten more chaotic without the presence of Tolkien. There have been more and more dimensional rifts opening on a regular basis. Additionally, there have been rumors that the Splugorth have been raiding further and further into and around the CS. Worse yet, there is a power vacuum now that Tolkien and its leading players are no longer on the board.

You are one of the Unlimited. Called such because you are empowered beyond imagination, you draw upon abilities once only possessed by a group of individuals, now as a single entity. Risen from the Chaos, you seek to find what has caused this disturbance, what has given birth to the need for the Unlimited.

During the Siege of Tolkien, vast amounts of PPE were definitely expended, both in the defense of the city and in the attempted offensive against it's enemies. What wasn't acknowledged was that there was also vast amounts generated through the countless deaths that occurred. This veritable sea of PPE swirled with all of the chaos, feeding back into the Siege. So...when the Siege ended and the victory was confirmed, that vast oceanic miasma of energy was no longer being fed nor accessed. Like a tide, the PPE receded, except it did not gently seep back. Instead, like a rubber band stretched taunt and let go, it snapped back...violently.

In theory, this is what happened during the Golden Age. This is what occurred when the Glitter Boy Brigade annihilated their opposition. It was the countless deaths that flooded the Earth with PPE that ripped open all of the Rifts across the planet, forever changing the Earth. This time though, the Rifts were already present...this time acting as bleed off valves...in a sense. Still, the amassed PPE was tremendous and needed somewhere to go. And like any force of nature, it found somewhere to go...into the Unlimited.

Flooded with massive amounts of PPE in an instant, the Unlimited were once normal beings.  The PPE tore through their being, igniting their bodies with incandescent energies, awakening something within them. Caster...Militia...Living...Dead, it did not matter what they were, or who they were. All that mattered now was that they had now became something more. They had become unfettered by their previous limitations. They had become...Unlimited!
